WAA I ATTORNEY Patented Aug. 15, 1944 v i- D? 6J'Clainf1s. ,This invention ran er new and useful improvements in inking rollers, and relates specifically to a sectional inking rollerfor lithography, gravure, and other types ofprintingpresses, v

The dominant object of my invention isto correct certain faults inherent in fulllength inking.

rollers which are fastened to ne shaft and there.- fore have all portions of their. areasrotating uniformly. In the process of printin ink is dis-; tributed from a fountain by a series of furnishing rollers, some of which aremetaland some of whichare composition. 'l'hejurning of each composition rolleris accomplished by a metal. roller which usually vibratesand which is gear driven. The composition roller, or; rol1ers, is placed against, or set against the ;metal roller, or rollers thereby receiving its turning powenylt is known to the pressmen that the form which the roller inks-,is composed ;of different sized pages, margins, and requires a different amount of ink indifferent sections becausecertainsec.-

It. should be clear that with the sectional roller pro-.v posed by this invention the defects inherent, in prior rollers willbe reduced, or eliminated,

Still further the invention proposes a.certaina' specific construction, of; the 7 newinking, roller. which is characterized by spaced pairs of bearings having inner races releasably clamped ,on theshaft of the roller, and outer races-with outwardly projecting radial flanges on their outer. edges cooperative with a rigid tube mounted between the outer races and bearing against the flanges and supporting the inkingroller, compo.v

The-new inking roller, in accordance with-this invention, includes arigid shaft l0. Spaced pairs of bearings have inner races l2 releasably clamped; on the shaft I'll. These bearings also haveputer races l3 which are provided with outwardly pro: jecting radial flanges-l4 on their outer edges. A rigid tube {5V is mounted on the outer races 13, andhas its ends engaging against the said flanges l.4'.- Inking composition material I6 is mounted.

screws I1. These set screws are threadedly en 1 gaged-throughprojecting portions l2'1fr0m the inner raceslZ. w An inking roller may comprise any number of. roller sections R which may be of identical lengths or different lengths, depending upon the composition of the form; The sections may easily be constructed merely by cutting the tubes 1 5-to required lengths. These tubes are then prepared. with the composition materiallfi. An alternai- I tive. construction would be to have long tubes with composition material and to out these" long tubes into smaller sections as required. The tubes l 5 with the composition material it thereon are; thenengaged between the outerraces ofbearings ll; These bearings H" maybe adjusted onthe shaft [0 by loosening the set screws I l and shifting them towards or away from each other. i Animportant feature of'jthe new inking? roller resides in the fact, that the different sections"- of the roller may rotate independently er 'ea'c'h other.- This eliminates stresses'due to diff'erent densities of different portions of the form. The" small sections ofjthe inking roller will not be subjected'to twisting; wrinkling'and other 'de structive tendencies. I

In Figs- 3-5 a modified form of the invention is-disclosed which is very similar to the' pr-ior' I form but: distinguishing in several respects; In accordance with .this .form, the rigid: shaft l 0= is provided with roller sections R which may be placed to have their adjacent ends in intimate contact with each other. Each of these sections R is constructed to embody the improvements inherent in this invention. Specifically, each indirectly mounted on the shaft [0. More spe}; cifically, each inner race 12 is slidably keyedona,

bushing 20 which is provided with a"fiang'ei"p or-T tion 2| which is releasably mounted on thesh'aft' In by the use of a set screw I1. Collars 2 2 are;

fixedly mounted on each bushing 20 on opposite sides to the inner race I2. Resilient "means; such 7 as expansion springs 23, are coaxially'mounted upon the bushing 20 and act between the collars 22 aridthe sides of the inner race 12." These expan sion springs" 23"re'siliently maintain the rollers R in fixed positions on the shaft l0. Fig. shows two ofthe roller sections R with their adjacent ends-contacting with each: other. If "desired, 'a roller section R may' be removed by gripping it and forcing it longitudinally or the shaft Ill in one direction so that the inner races l2 are forced longitudinally, exposing an end of one of the bushings 20. This eiiposedfe' nd -'will eX'p'ose o'ne of the set screws I! which maybe loosenedto free the bushing'from 'tliejshaft it]. Then the roller sections R may' I be moved longi tudinal ly in the opposite direc'tion 'to similarly expose the other set screw I! 'so' that the other bushin'g'Zl) may be loosened; Now the roller'section is free to be shifted along onthe shaft l and removed,as d'e'siredj I Another feature inherent in-this' form of the invention is the provision of means for'indica't ing whether or not the bearings H are working satisfactorily in the event that there is any binding; Then rotations are transmittedto theshaft I0 and the indicator will operate. Specifically, the shaft ll! is turnably supported in the bear ings :25 of'the frame 26 of the "printing ress The shaft II] has a projecting end provided with a finger'21 which is cooperative with a switch 28 when the shaft I0 turns. This switch 28 is connected in an electrical circuit 29 having an audible or visible signal 30. Normally, when the roller sections R are workin satisfactorily, the shaft [0 will not turn and the finger 21 will not engage the switch 28. However, when it does engage the switch, the switch is closed, which closes the circuit 29 and sets the indicator 30 into operation. a While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifica-- tions coming within the scope of the invention as defined in the appended claims.
